A derecho debrief: Not even a scientist/storm chaser expected the August 10 storm
Bill Gallus, an Iowa State storm expert (and chaser), was as surprised as anybody by the Aug. 10 derecho that blew across Iowa and the Midwest. He expects researchers will take a good look at why the violent, straight-line winds didn't show up in forecasts. And does a warmer climate mean more of these storms are coming? Gallus said it's hard to say for several reasons, including the fact there are too few of the storms to establish much of a trend line.
Iowa State to open new COVID-19 testing center
Iowa State University is expanding its COVID-19 testing, case management and contact tracing efforts to manage infection on campus. A new testing center will open in the next week in Johnny’s at Hilton Coliseum, and the university is more than doubling the number of contact tracers and case managers who notify and support ISU students, faculty and staff who test positive or were potentially exposed to a positive COVID-19 case.
Engineers use heat-free technology to make metallic replicas of a rose's surface texture
Iowa State's Martin Thuo and his research group have developed technology to make metallic replicas of soft, natural surfaces such as rose petals. The team's metallic surfaces retained properties of the originals, including a rose petal's sticky, yet water-repelling textures.
Plant scientists study the interaction of heat stress responses in corn
A new study shows how two responses in separate locations inside plant cells work in concert to help corn plants respond to heat stress. The research was made possible by the Enviratron, an innovative plant sciences facility at Iowa State University that utilizes a robotic rover and highly controlled growth chambers.
COVID-19 cases reported for first week of classes
Iowa State University will provide weekly updates on COVID-19 test results. The data will include testing conducted at Thielen Student Health Center (TSHC) for students, faculty and staff who were symptomatic or exposed to someone who tested positive, as well as test results from the athletic department.

Biomedical scientists piece together how medication paralyzes parasitic worms
A new study upends the widely held belief that a medication used to treat lymphatic filariasis doesn’t directly target the parasites that cause the disease. The research shows the medication, diethylcarbamazine, temporarily paralyzes the parasites.

Book examines influence of racism on voting rights
There is greater awareness today of structural racism in the U.S., but Americans are still split on the impact it has on the voting rights of underrepresented groups, according to a new book co-authored by an Iowa State University political scientist. The book, “Ignored Racism” examines the history of hostility toward Latinos and how it influences attitudes about voting rights.
Searching the ancient depths of a reptilian genome yields insight into all vertebrates
An Iowa State University scientists contributed to a global effort to assemble the genome of the tuatara, a rare reptile species native to New Zealand. The tuatara genome sheds light on the genomic structure of a huge range of species, including humans.

Iowa State students begin moving into the residence halls
New students are starting to move into the residence halls at Iowa State University. The move-in process for fall is starting earlier than usual and spread out over a longer period of time to help maintain physical distancing in the residence halls.
